[MosinMaster11]

I bought 91/30 mosin nagant and i fired it the other day at the range and the iron sights are all over the place. at 25 yards it had a decent gruop bout 1 o'clock but about 6 inches high i was aiming right dead center i was a at a bench rest so. Then i moved down to the 100 yard range and fired there i didnt evn hit it then i aim at the top of the wood which i s abot 2 feet low from the bulseye and that went about 3o'clcom and about the right hieght just to the right and 3 o'clock can anyone help me please what i can do or whats going on. i will get a scope sooner or later.

First, go back to the 50 yard range and set up an oversize target. With the rear sight (the V notch carrier) in the most rearward position, bring the front sight up until the blade (pin) top is just under the bulls eye. Hopefully you are supporting the rifle on sandbags and shooting from a bench. Squeeze the trigger and note the point of impact. Follow up with a couple of more shots exactly as before. This should give you a group from which to adjust. At fifty yards you will need to adjust rear sight to hit approximately 1.5" high, on my 91/30, my elevator is half way between the #1 and #2 on the ladder. To adjust the windage you will have to move the front sight either left or right by tapping the front sight(it is in a dovetail and can be moved with a small hammer and dowel, put masking tape across the barrel and mark with pen BEFORE you move the sight for reference) in the opposite direction of the point of impact. If it shoots left, tap it right...a little goes a long way. After dialing it in, shoot one more group at fifty, clean the barrel (brush, solvent, patch dry) and move to the 100.

Good advice but the directions for adjusting the front sight are backwards, you need to move the sight the same direction as the error.... if it hits right then move the front sight to the right, if it hits left then move the front sight to the left.

EDIT: next time I'll read the OP more carefully.

For it to shoot a foot or foot and a half high is very typical of a wartime manufacture 91/30. I don't think they cared much about the elevation of the sights, they just sent them out as fast as they could to fill the hands of another conscript.

You can use build up the front sight to bring your elevation down using somethig like JB-weld, or you can put a scope on the rifle.

Mojo sights are another option, though replacing the front post with a nail and filing it to height is cheaper.

ok thnx guys i did som research today and they said they shoot high or have been know to shoo thigh so im gonna file down the front sight and try that and im gonna get a scope eventually thnx again i really did not know wat to do and if u guys can find a pu scope for cheap please let em know i have only found them for 200 bucks and higher so let me know i would really appreciate it

If you file down the front sight, it will shoot even higher....

Do a search on 'darrel's scope mounts' -they are a high quality scout mount that fits on the rear sight base, a lot cheaper than than a PU mount, and doesn't require any gunsmithing.

The sights on Military rifles are a little different than hunting rifles.

On the Mosin Nagant the bottom setting is for about 150 yards out. At 100 yards if you set the sights to the bottom of what you want to hit you will be close to the center of that target.

Also, the barrel might be fouled. I suggest buying a good solvent for removing copper fouling and give the barrel a good cleaning. I was lucky enough to get a great barrel on my 91/30 but the M44 had to be cleaned, and cleaned well. I suggest soaking the barrel with something like Sweet's 7.62 Bore Cleaner overnight and then go at it with a good bore brush until you clean out all the junk that's probably in there. That should improve the accuracy a ton...
